The Great Lakes Graphics Association is hosting its first in its 2021 Quarterly Environmental Update webinar series on February 4. SCS Engineers staff will present on critical regulatory issues that affect the industry.
SCS Engineers now provides the Augusta Environmental Services Department with engineering, environmental and testing, and Construction Management & Quality Assurance Services at the Deans Bridge Road Landfill, in Blythe, Georgia. The facility operates under the State of Georgia Environmental Protection Division as a Subtitle D Landfill, accepting up to 1,500 tons per day of waste. Active and closed sections of the landfill comprise approximately 1,177 acres of property. Some additional acreage contains ancillary facilities such as office and maintenance buildings, customer drop off area, sediment ponds, roads, and leachate holding facilities. The Augusta Department of Environmental Services is responsible for the landfill facilities, solid waste management planning for Augusta, and all residential solid waste collections. Additionally, the Department is responsible for the Augusta Brownfield program and other environmental compliance issues.
Landfills are carefully engineered facilities closely regulated and monitored to ensure they have the protections necessary to prevent contamination of groundwater, air, and adjoining land. Best landfill management practices include collecting and treating leachate – the water that passes through a landfill. The methane gas naturally produced from decomposing landfill waste is collected and converted into various forms of energy – including compressed natural gas. This alternative fuel powers Augusta Solid Waste trucks or is a substitute for pipeline natural gas.
The Department consolidated all landfill services assigning them to SCS Engineers, a professional environmental consulting firm with over 50 years of experience in performing landfill site acceptability studies, landfill design services, landfill environmental compliance activities. The firm was already engaged in the Landfill’s Gas Collection and Control System (GCCS) expansion. The consolidation of services provides a more cost-effective approach for permitting, design, operations, monitoring, and maintenance. The comprehensive SCS team is a uniquely qualified and experienced full-service consulting and engineering team with demonstrated relevant field experience in Georgia. Leading the team is Sowmya Bulusu, a Georgia Professional Engineer, with over 12 years of landfill engineering performed in accordance with the Environmental Protection Division (EPD) of the Georgia Department of Natural Resources, the Georgia Solid waste management Act, and other applicable federal, state, and local rules and regulations. As the Project Director, Carlo Lebron is a registered Georgia Professional Engineer for 15 years bringing over 21 years of experience on over one hundred solid waste projects.
“The SCS team brought the five-year permit review submittal package in early, giving Georgia’s Environmental Protection Division plenty of time to deem it administratively complete,” stated Sowmya Bulusu. “Working with our field technicians, we quickly identified and brought at-risk gas wells into compliance, used our drones to provide an aerial survey of the entire landfill, saving Department funds.”

SCS Engineers’ newest environmental technology application is for use at solid waste facilities and landfills. These sites require specific monitoring and analyses of groundwater and liquids, landfill gas – LFG, and surface emissions critical to facility infrastructure and the environment.
“We work side-by-side with our clients at hundreds of facilities nationwide. SCS MobileTools® supports operating decisions, whether our client is managing one site or hundreds,” states Pete Carrico, senior vice president and assistant director of SCS Field Services.” The App’s interface gives clients quick access to information that drives critical operating decisions and provides data for corporate directives and landfill gas OM&M programs for regional or national operations.
SCS MobileTools® is the iOS and Android mobile interface for the SCSeTools® platform. Access to data to make informed decisions is especially valuable when technicians are in the field, or operators are working remotely. Landfill and solid waste facility owners, operators, and technicians use the new application to observe system and environmental activity securely and in real-time on a mobile phone or device.
Featuring state-of-the-art technology, SCS MobileTools® provides users the ability to interact with a site or facility data, including site-specific monitoring and exceedance metrics for landfill gas, liquid levels, and surface emissions. Responsive, touch-enabled flow data charting is accessible, illustrating flow targets, reading dates, flow rates, and historical flow data analysis.
When compared year-over-year, generation and disposal trends produce information critical to assessing optimal options and solutions that represent significant savings for landfill gas Operations, Maintenance & Monitoring – OM&M programs. For this reason, the savings compound for regional or national operators.
For instance, monitoring and analyzing landfill gas generation and collection data against modeled estimates are valuable information. SCS MobileTools® handles the input, analysis, review, and export of landfill gas flow and related information, specifically flow rates, impacts on gas collection (e.g., extraction well liquid levels), and analytical data for data collection points.
In SCS’s release pipeline, SCS MobileTools® will include mapping and visualization functions in early 2021. SCS MobileTools® is available for download on the Apple App Store for iPhones and iPads, Google Play for Android.

CERLCA Jurisdiction and PRP Definition
A recent Meyers | Nave publication discusses the Supreme Court’s April 20, 2020 decision in Atlantic Richfield Co. v. Christian. The firm suggests the decision adds another layer of complexity to the Comprehensive Environmental Response, Compensation, and Liability Act – CERCLA, liability issue. The decision opens the door for state courts to hear claims that challenge EPA-defined approved clean-ups and has the potential to expand the “potentially responsible party” – PRP class for current “owners” of a “facility.”
The Court’s decision introduces new considerations into CERCLA liability analysis and settlement strategy. The Court’s holding will have many immediate ramifications, including the following:
Clean Water Act Developments
In April, the courts and federal agencies announced major developments significantly affecting regulation under the Clean Water Act – CWA and how the CWA may be applied in the future.
Each of these developments could have far-reaching implications for regulations under the CWA. Assuming the 2020 Rule withstands legal challenges, it is seen as favorable for industry and other regulated entities, while the two judicial decisions are perceived as problematic for such entities. Davis Graham & Stubbs describes each development in more detail in the firm’s recently published article.
MATS Supplemental Cost Finding and Clean Air Act RTR
On April 16, 2020, the U.S. Environmental Protection Agency (EPA) finalized the 2016 Supplemental Cost Finding for the Mercury and Air Toxics Standards – MATS, for coal- and oil-fired power plants, consistent with a 2015 U.S. Supreme Court decision. The agency also completed the Clean Air Act-required residual risk and technology review – RTR, for MATS. According to the EPA power plants are already complying with the standards that limit emissions of mercury and other hazardous air pollutants (HAPs), and this final action leaves those emission limits in place and unchanged.
However, with this final action, EPA is not removing coal- and oil-fired power plants from the list of affected source categories for regulation under section 112 of the Clean Air Act, consistent with existing case law. Those power plants remain subject to and must comply with the mercury emissions standards of the MATS rule, which remains fully in effect notwithstanding the revised cost-benefit analysis.
In addition, EPA has completed the required RTR for MATS and determined no changes to the rule are needed to further reduce residual risk. The RTR satisfies the statutory requirements set out by Congress in the Clean Air Act. More information is available on EPA’s Mercury and Air Toxics Standards website.
Proposal to Retain NAAQS for Particulate Matter
On April 14, 2020, the U.S. Environmental Protection Agency – EPA announced its proposal to retain, without changes, the National Ambient Air Quality Standards – NAAQS for particulate matter (PM) including both fine particles (PM2.5) and coarse particles (PM10).
According to the EPA because of Clean Air Act programs and efforts by state, local and tribal governments, as well as technological improvements, average PM2.5 concentrations in the U.S. fell by 39 percent between 2000 and 2018 while average PM10 concentrations fell by 31 percent during the same period.
EPA states it is following the principles established to streamline the NAAQS review process and to fulfill the statutory responsibility to complete the NAAQS review within a 5-year timeframe. More information about the rule can be found at EPA’s: National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM) Pollution website.
EPA will accept public comment for 60 days after the proposed standards are published in the Federal Register. EPA plans to issue the final standards by the end of 2020.
U.S. Greenhouse Gas Emissions and Sinks Inventory Announcement
The Environmental Protection Agency’s annual report, “Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2018,” provides a comprehensive look at U.S. emissions and removals by source, economic sector, and greenhouse gas – GHG. The gases covered by this inventory include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. The inventory also calculates carbon dioxide emissions that are removed from the atmosphere by “sinks,” e.g., through the uptake of carbon and storage in forests, vegetation, and soils.
On April 13, 2020, the EPA’s comprehensive annual report on nationwide GHG emissions released to the public. It shows that since 2005, national GHG emissions have fallen by 10%, and power sector emissions have fallen by 27%.
“While there was a small rise in emissions due to weather and increased energy demand from the prior year in this report, based on preliminary data, we expect next year’s report to show that the long-term downward trend will continue,” said EPA Administrator Andrew Wheeler.
According to the announcement, annual trends are responsive to weather variability and economic conditions. Year-over-year, national GHG emissions were 3% higher in 2018 than the prior year, due to multiple factors, including increased energy consumption from greater heating and cooling needs due to a colder winter and hotter summer in 2018 compared to 2017.
According to environmental and research groups, driving the drop’s long-term downward trend is chiefly due to a shift away from coal power generation. The 2019 drop was driven by a nearly 10 percent fall in emissions from the power sector, the biggest decline in decades [Rhodium Climate Service]. Utilities are closing coal plants in favor of cheaper natural gas and renewable energy.
Emissions from industry rose slightly last year, and are now greater than those from coal-fired power plants, most driven by a strong economy. Emissions from buildings were up, and emissions from other sectors of the economy collectively grew by more. The shift to lower-carbon energy is largely restricted to the electricity sector, and in order to meet international and state goals, state policies continue to target other sectors that collectively make up a majority of U.S. emissions.

EPA has issued a revised NESHAP standard for municipal solid waste landfills. The new rule reflects EPA’s conclusions regarding the residual risk and technology rule, resolves confusion created when the previous rule was not updated at the same time as the landfill NSPS and updates landfill gas well head criteria for temperature. EPA is also clarifying that the standards are applicable during periods of startup, shutdown and malfunction, and requiring electronic reporting of performance test results.
This action finalizes the residual risk and technology review (RTR) conducted for the Municipal Solid Waste (MSW) Landfills source category regulated under National Emission Standards for Hazardous Air Pollutants (NESHAP) contained within 40 Code of Federal Regulations (CFR) Part 63, Subpart AAAA. Additionally, the U.S. Environmental Protection Agency (EPA) is taking final action to:
The EPA is also finalizing minor changes to the MSW Landfills NSPS and Emission Guidelines (EG) and Compliance Times for MSW Landfills contained within 40 CFR Part 60, Subparts XXX and Cf. Specifically, the EPA is finalizing provisions to the most recent MSW Landfills NSPS and EG that would allow affected sources to demonstrate compliance with landfill gas control, operating, monitoring, recordkeeping, and reporting requirements by following the corresponding requirements in the MSW Landfills NESHAP. According to EPA, these final amendments will result in improved compliance and implementation of the rule and eliminate some of the confusion created by the previous version of the EPA rule.
We’ve pulled this information from the Final Amendments to Air Toxics Standards for Municipal Solid Waste Landfills and SCS will publish an SCS Technical Bulletin on our blog and social media sites. Please contact your Project Manager for details specific to your operation.
Approximately 738 MSW landfills are subject to the NESHAP.
On February 25, 2020, EPA finalized amendments to the 2003 NESHAP for MSW Landfills. EPA issued air toxics standards for the MSW Landfills source category in 2003 that established emission limitations based on maximum achievable control technology (MACT) standards for hazardous air pollutants (HAP) from major and area sources.
The rule required MSW landfills greater than 2.5 million megagrams (Mg) and 2.5 million cubic meters with uncontrolled emissions greater than 50 Mg/year of non-methane organic compounds (NMOC) to install and operate a gas collection and control system (GCCS). Most emissions from MSW landfills come from the continuous biodegredation of the MSW. Landfill gas contains methane, carbon dioxide and more than 100 different NMOC, including, but not limited to, vinyl chloride, ethyl benzene, benzene and toluene.
Based on the RTR, EPA is finalizing no changes to the existing standards because the agency determined the risks to be acceptable with an ample margin of safety to protect public health and the environment. In addition, EPA did not identify any new cost-effective emission controls for MSW landfills. However, EPA is finalizing several minor amendments to reorganize and streamline requirements for MSW landfills that will improve the clarity, compliance and implementation of the rule. These include:
The Clean Air Act (CAA) requires EPA to regulate toxic air pollutants, also known as air toxics, from categories of industrial facilities in two phases. The first phase is “technology-based,” where EPA develops standards for controlling the emissions of air toxics from sources in an industry group or “source category.” EPA bases these MACT standards on emission levels that are already being achieved by the best-controlled and lower-emitting sources in an industry. Within 8 years of setting the MACT standards, the CAA directs EPA to assess the remaining health risks from each source category to determine whether the MACT standards protect public health with an ample margin of safety and protect against adverse environmental effects. This second phase is a “risk-based” approach called residual risk. Here, EPA must determine whether more health-protective standards are necessary.
Every 8 years after setting MACT standards, the CAA requires EPA to review and revise the standards, if necessary, to account for improvements in air pollution controls and/or prevention and to address any residual risks that still remain after the MACT is implemented.
The CAA requires EPA to assess the risk remaining after application of the final air toxics emission standards; known as a residual risk assessment. Based on the completed risk assessment, available health information, and associated uncertainties, EPA determined risks from the MSW Landfills source category are acceptable and provide an ample margin of safety to protect public health. EPA estimates the maximum individual lifetime cancer risk for inhalation for the source category to be less than 10-in-1 million.
The CAA requires EPA to assess, review and revise air toxics standards, as necessary, taking into account developments in practices, processes and control technologies. The technology review of the standards for MSW Landfills did not identify any developments that would further reduce HAP emissions beyond the original NESHAP.

National Emission Standards for Hazardous Air Pollutants: Stationary Combustion Turbines Residual Risk and Technology Review 40 CFR Part 63
This action finalizes the residual risk and technology review (RTR) conducted for the Stationary Combustion Turbines source category regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, EPA is taking final action addressing requirements during periods of startup, shutdown, and malfunction (SSM)
and to add electronic reporting requirements.
The EPA is finalizing its proposed determination that the risks from this source category due to emissions of air toxics are acceptable and that the existing NESHAP provides an ample margin of safety to protect public health. The EPA is also finalizing its proposed determination that EPA identified no new cost-effective controls under the technology review that would achieve further emissions reductions from the source category.
This final rule is effective on March 9, 2020. The incorporation by reference (IBR) of certain publications listed in the rule is approved by the Director of the Federal Register as of March 9, 2020.
